BOOT ORv SHOE HEEL.

SPECIFICATION forming part of Letters Patent No. 727,898, dated May 12, 1903.

Application iiled June 29, 190].

'end I produce a heel by compressing pulpsuch as leather, wood, paper, or other fibersin a mold and simultaneously form a cavity or chamber in the upper portion of the heel, and Within said cavity or chamber I place a metallic shell or hollow body, and by preference I mold the pulp upon such shell While forming the heel. This shell stiffens the malerial of the heel and enables the walls of the heel surrounding its cavity to be relatively v thin.

A further portion of my invention relates to improved means for holding a heel of the character above described upon a shoe and also means for attaching a lift or bottom layer to the heel, and to this end I provide a heel with a shell, as before explained, and upon said shell from its upper edges extend a series of teeth or prongs which are adapted to pass through the shank or sole portion of a shoe and to be clenched therein. To attach the litt to the bottom of the heel, I provide downwardly-extending prongs from the shell, which are adapted to pass into the lift when the latter is pressed or forcedagainst the molded portion of the heel.

Reference is to be had to the accompanying drawings, forming part hereof, wherein- Figure l is a perspective View of heel, partly broken,embodying my invention. Fig. 2 is a perspective view of the shell for .the heel provided With the attaching-prongs, and Fig. 3 is a partly-broken perspective view of a shoe provided with my improved heel.

Similar numerals of reference indicate corresponding parts in the several views.

In the accompanying drawings the numeral 1 indicates a heel which is provided with a cavity or c hamber 1f, entering the same from the upper surface, forming a bot-tom and side walls, and I produce the heel by compressing Serial No. 66,470. (No model.)

pulp in a suitable mold, While at the same time forming the cavity. The pulp to be used is preferably leather-pulp, and, if desired, scrap leather may be used in wellknown manner and compressed to the required degree and allowed to harden. Woodpulp, paper-pulp, or other fibrous material combined in well-known manner with any other necessary elements may be used instead of the leather-pulp and compressed as may be found necessary. l

Within the cavity 1a of the heel I place a shell or casing 2, made of suitable metal drawn or otherwise formed to the desired shape or size'and adapted to be irmly united to the walls of the heel. By preference the shell 2 is placed in the mold at the time the heel is being moulded or formed, so that the pulp will be compressed firmly upon the shell and a tight connection made between the two. strengthens the heel and enables the walls of the same to be relatively light.

The heel formed as above described may be secured to the shoe in any desired manner.

In Figs. 2 and 3 I have shown means for securely uniting the heel to a shoe and for attaching a lift or bottom layer to the heel. In this case the shell 2 is provided at its upper edge with any suitable number of prongs or teeth 2a, Which'project above the upper sur- 'Ihe casing or shell 2 materially4 face ofthe heel and are adapted to be passed through the shank or sole o'f the shoe 3 and to be clenched within the shoe, as indicated Iin Fig. 3. l be made integral Wi'ththe 'material lot the shell 2, which maybe done in any Well-known manner. The heel being firmly bound to the shell and the shell being attached to the shoe,

as described, enables the heel to be readily secured to the shoe, and by having the prongs pointed it will be apparent that by merely pressing them against the bottom of the shoe they will pierce the latter and can be clenched in suitable manner. n

While a bottom lift or layer 4 can be applied to the heel by nailing it thereto, I preferably provide the shell 2 With a series of downwardly-projecting prongs 2b, which may be formed by cutting them out of the material of the shell, as indicated in Fig. 2, and when the heel is molded upon the shell the By preference the prongs 2a Will prongs will be permitted to extend beyond the lower surface of the heel and can project through the bottom wall of the heel, as indicated in Fig. 3, and the lift 4 can be pressed upon the prongs 2", or vice versa, and the latter will pierce the lift, and thus the lift will be attached to the heel without the necessity of using separate nails. As indicated in Fig. 3, the prongs need not be long enough to pass entirely through the lift 4.

The advantages of my improvements are such that the usual separate layers nailed together for a heel are dispensed with, the heel is made lighter` for a given size, and when leather-pulp is used the labor of shaping the various layers is dispensed with, as the heel will come from the mold shaped, and with leather-pulp the heel can be burnished and polished the same as the layers, and the necessity of drilling holes through the heel to receive nails is overcome. The shape of the cavity or chamber l may be such as found most suitable, and the shape of the shell 2 will approximately correspond thereto.

Having now described my invention, what I claim isl. As an article of manufacture, a heel for boots or shoes comprisingcompressed pulp or scrap material having the sides and bottom wall integral and provided with a cavity and a shell Within said cavity, said shell having prongs projecting through the bottom wall of the heel, substantially as described.

2. As a new article of manufacture, a shoe having a heel comprising pulp or scrap material and having the sides and bottom wall integral and provided with a cavity and a shell within said cavity, said shell being provided with prongs that pass outwardly from the heel into the bottom of the shoe and are clenched therein, and with prongs at the opposite end of the shell that pass into the bottom Wall of the heel, substantially as described. l

3. As a new article of manufacture, a sho provided with a heel comprising pulp or scrap material and having the sides and bottom wall integral and provided with a cavity and a shell within said cavity, said shell being provided with prongs that pass into the bottom of the shoe and are clenched therein, and with prongs at the opposite end of the shell that pass through the bottom wall of the heel, and a lift secured upon the outer side ofthe bottom of the heel, the lower prongs projecting into said lift, substantially as described.
